Passing signon via URL

[mpflug]

Hi All,
  I have a datasource that has multiple signons configured.  MY sdk app runs reports in an Iframe and I can run the report by going to a url like:

http://<server>/cgi-bin/mod2_2_cognos.dll?b_action=xts.run&
m=portal/launch.xts&
ui.tool=CognosViewer&
ui.action=run&run.prompt=false&
ui.object=CAMID{reportcamid}&
cv.toolbar=false&
run.verticalElements=30

I haven't been able to find anything in the doc on this, but does anyone know if its possible to pass a signon in the URL?

I'm not sure if this helps, but your authenticated user only sees the signon they have access to. So if you have three signons and your authenticated user can see all three, then you will be prompted. However if you apply security to two of them, effectively hiding them from the user, they will only see one signon and will automatically use that.

Do you want to select signons for security reasons or is it to switch schemas in Oracle... something like that?
